ERNEST HEDENSKOOG, F MUSKEGON, MICHIGAN, ASSIGNOR TO THE BRUNSWICK BALKE-COLLENDER COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF- DELAWARE.

t ,ieasaa.

To all whom it m concern:

Be it known that I, ERNEST Hnonnsnooo, a citizen of the United States, residing at Muskegon, in the county ofMuskegon and State of Michigan, have invented certain new and useful Improvements in Automatio Pin-Setting Machines, of which the follows ing is a specification.

This invention has for its object broadly to dispense with the services of a pin boy for setting pins on the alley and returning the balls to the players position.

In the game of tenpins as generally played, ten pins are arranged in triangular formation at the end of the alley in front of the pit. The player has the right to roll two balls; If the first ball knocks down all the ten pins, the player scores a strike; if he knocks down some of the pins with his first ball and all of the remaining pins with the second ball, he; scores a spare; if any pins remain standing after the player rolls both halls, lie-only scores the number,

of pins knocked down. 4 lit has been customary in the past to station a pin boy in the pit of each alley to place the balls on the track for return to players position, to remove the fallen pins called deadwood that may remain on the alley or in the gutters alongside the alley, e-and to set thepins as required. Attempts have been made to expedite the work of the pin boy inyarious ways and in recent years, pinqsetters have come into general use. One form of setter consists of a vertically movable frame, provided with pockets for the pins and into which the pin boy throws or places the pins While the setter is at rest on the alley bed and then operates suitable 40 mechanism to elevate the setter, leaving the pins set in proper position ontheir spots. Another form of settencomprisesa vertically movable frame which is filled with pins while the setter is in elevated position and which is then operated to descend and set the pins on their spots and then -rise to its normal elevated position. These machines are employed to a considerable extent at present because they facilitate and expedite the work of the pin boy, and also through the distributer and pin setter. "Fig. v8 is an enlarged front elevation of the cam provided to control the operation of the pin for accurately setting the pins on the spots.

Some efforts have been made to dispense with the services of the pin boy by attaching cords to the pins which can be operated Specification of Letters Patent.

by the players but it is not permitted in the standard game of tenpins to restrainor re strict the freedom of movement of the pins and such devices have not proven practiea-.

ble or commercially satisfactory.

This invention has for its object to prov1de an automatic machine which is wholly under the control of the player and which dispenses with the necessity for a pin boy by doing all of the work heretofore done by pit to the setter frame; and for setting the pins in the proper position on the alley bed when the latter is cleared.

A further object of the invention is to provide a pin setting machine which will perform these operations rapidly so that the balls will be returned promptly and the deadwood removed and the pins re-set immediately upon actuation of the controlling de: vices by the player thereby permitting substantially continuous and uninterrupted play upon the alley without the usual delays incident to the pin setting methods at present in vogue. 1

Other objects and advantages of the in vention will be apparent as it is better understood from the following description considered in connection with the accompanying drawings disclosing a preferredview of a pin setting machine embodying my invention showing it in operative position at-tbe pit end of a bowling alley; Fig. 2 is afront elevation of'the same; Fig-3 is a vertical sectional view on the line 3--3 of Fig. 2; Fig. 4. is a vertical sectional view on the line 4-4 of Fig. 1 showing the means for elevating the pins into position to be fed into the distributing frame and for delivering the balls to the return track; Fig. 5 is a top plan view of the distribute m Fig. 6 is a setter. Fig. 9 is an enlarged view of the 30 walls 22. 'At the rear of the.'alley is the cam controlling the movement of the sweeper and of the mechanism mounted between it and the cam controlling the movement of the pin setter.

' assembly shelf when a full set of pins has been assembled thereon.

Referring to the drawings I have shown one preferred embodiment of my invention installed in position at-the pit end of a regular bowling alley. The bowling alley (Figs. 1-3) is. of the usual form comprising the alley bed 20, the gutters 21 and side usual swinging bumper 23, supported above and at the rear'of the pit 24 in. position to break the force of the balls and flying pins a nd cause them to drop into ,the. 'pit.

The various parts and mechanisms of the pin settingmachine are mounted in a suitable frame 25jwhichis supported upon the side walls 22 of the alley. These parts and mechanisms will be described as nearly as possible in the order in which they are called upon to perform their duties.

Assuming that the pins have been set the first function of the pin setting machine will be toremove the deadwood after the ball has been rolled by a player. This is i done by the pinfsetter frame 26 and sweeper 27, the operation consisting in sweeping back into the pit all deadwood on the alley or in the gutters if all pins have been knocked down, and in lifting the standing pins, if any remain standing, to permit the sweeperto remove the deadwood and then returning the standing pins to the exact position from which they were lifted: Both the sweeper and the pin setter frame, as well as numerous other parts, are actuated from a continuously operating motor 28 mounted upon a platform 29 which is supported at the front of thepin setting machine by the frame 25., The pin setter frame 26 is verticall'y movable and is supported from the :transverse horizontal member 30 of the frame 25bya. plurality'of chainsBl trained over pulleys 32, which are jollrnaled in A pair of guiding rods 38 are rigidly secured to the pin setter frame and extend outwardly therefrom. passes through and is guided by a bearing plate 39 secured above the pin setter frame. The upper end of one of the rods 38 is pivotally connected by a link 42 with a lever 43 which is journaled at its fulcrum 43 in suitable bearings44' extending above and mounted on the platform 29. The oscillation of this lever about the bearings 44 lifts and lowers the pin setter frame when it is desired to pick up the pins preparatory to removing the deadwood froni the alley and "when it is desired to return them again to position after this operation has been performed. The shaft 45 upon which the armatureof the motor is rigidly fixed, is provided with a worm 46, whichcontinuously Each of these rods operates agear 47 mounted upon an end of the horizontal shaft 48. This shaft is provided at its other end with a bevel gear disks 53 and 54 are loosely mounted on the shaft 52. These disks transmit the power to and furnish the control for; the movements both of the sweeper and of the pin setter frame. The cam disks 53:11.14 ,4 are normally at rest and are adapted" ilpon desired occasions to be locked to the shaft 52 to rotate therewith. These disks are fixed ipon a collar 55 encircling .the shaft 52 which coiiperates atone end with a friction clutch collar 56 slidablenpon the shaft 52. The slidable collar 56 is connected to one end of the lever 57 fulcrumed at 61,and

carrying at its other end an armature 58 for a magnet 59. When this magnet is energized the armature pulled toward the a magnet thereby swinging the lever. on its fulcrum to move the collar 56 into engage- .ment with collar 55, thus throwin inthe clutch. It is desirable, as will elater understood, that the disks make one complete revolution for each operation of the pin setting machine and to this end a.,r0ller 62'is providedupon the end of the lever 57 adjacent the armature 58 which normally rests a de ression 63 in the. outer cylin-.

drical face 0 the disk 54. When the lever is movedto throw in the clutch by the mag- .aaaopea net the roller is pulled from the depression and as the disks rotate rolls upon the cylindrical surface of the disk 54 positively main- L taining the clutch in engagement until the depression is again in position to receive the roller. A spring 60 is connected to the lever 57 and pulls the lever about its fulcrum when the depression 63 arrives at this point. The roller in again entering the recess 63 permits the spring to move the lever about its fulcrum to throw out the clutch and prevents excessive movement of the disks.

Upon theend of the arm of the lever 43, which is adjacent the cam disks 53 and 54, is provided a roller 64; (Fig. 8), normally resting in an annular groove 65 in the cam disk 54 and concentric therewith. In this disk are provideda pair of grooves 66 and 66 each normally closed at .its end by fingers 67, 67 and 68. The fingers 67, 67' through a suitablemechanism to be later described, open and close the grooves to direct the roller successively through the grooves 66 and 66 or to maintain it in the" groove 65, while the fingers 68 are merely held in closed )osition by means of springs 69 mounted between the disks. When the roller 64 is diverted into the groove 66, the lever 43 is moved about its fulcrum lowering the rod 38 and, pin setter frame 25.

Mounted on the under side of the pin set-. ter frame and directly above the pin spots upon the alley bed are ten lifting magnets .71 (Fig. 7) adapted to engage the tops of the ten pms or as many of them as are left standing pins the magnetic attraction between the magnets and the elements 71' will I lift the pins when the frame is moved upwardly as the roller 64 approaches the groove 65 at the end of its passage through;v

the groove 66, all of which is more fully the sweeper is as follows: The blade 73 0f described hereinafter. After the standing the sweeper is provided at each end with an upwardly extending bent arm 7 6 which is pivotally connected at its upper end to the end of an arm 7 6, rigidly secured to a shaft 77, eXte1-.ding transversely of the pin setting machine and journaled at its ends in the frame 25. A lever 81, fulcrumed' at 81' concentrically with the le er 43, is pivotally connected by a link 7 9 with an arm 7 8- rigid on the shaft 77. Upon the end of thelever 81, adjacent the cam disks is provided a roller'82 (Fig. 9), which moves in an annular groove 83 in the face of the cam disk A groove 84 in the face of the disk 53 communicates at its end with the groove 83 to carry the roller 82 inwardly toward the center of the cam. A fingerv 85 at the forward end of the groove 8d is adapted to be operated to divert the roller from the groove 83 into the groove 84;, which controls the movement of the sweeper after the pin setting machine has lifted the pins from the alley bed as just described. When the roller 82 passes through the groove 84, the lever 81 is moved about its fulcrutn and through the link 79, rod 77, arms 76 and 78 the sweeper is lowered and moved rearwvardly over the alley bed to sweep into the pit the pins which have fallen upon the alley and in the 'gutters. The movement of the sweeper is restrained by means of a slotted link 86 pivoted at one end to .the'arm 75 and embracing a pin 87 upon the arm 76 at the other end.

A sliding weight 89 (Fig. 3) is carried by an arm 68 mounted rigidly" upon the shaft 77 to counterbalance the sweeper 27. The weight is caused to slide upon the arm 88 by a fixed guide 91 on which the weight travels and which serves as a cam to increase and decrease the leverage provided by the weight a as may be required at different points in the swing of the arm 88.

The grooves 66, 66 and 84 in the disks (Figs. 8, 9) are normally closed by the fingers 67, 67 85, and are adapted to be opened when it is desired to remove the deadwood by a mechanism located between and above the disks which will now be described (Figs. 9, 10). -The two fingers 67, 67 and the finger 85 are rigidly mounted respectively I upon a pair of stub shafts 92 anda stub shaft 93, each of which extends through and is journaled 'in the disk carrying its finger. Arms 99 are mounted on the stub shafts 92 between the disks and are pivotal'ly connected at their end to a link 94so that the two fingers 67, 67 must move in unison. A link 96 is connected at one end with an arm 95 mounted on stub shaft 93 and at its othe end with an arm 95 mounted on stub shaft 93'. The arms 90 cause both fingers 67-, 67 to open or close the. grooves 66 and 66 at the same time,-and connections between the links 94: and 96 cause the finger 65 to open and close with the fir gers 67, 67. A preferred connection between the two links 9 and 95 consists of an arm 97 rigidly connected to the stub shaft 92 of the finger 67,

arm 97, so that .the longitudinal movement of the link 96 will produce a corresponding longitudinal movement of the link 94.

When it is desired to remove the deadwood the link 96 is moved substantially longitudinally from the normal position shown in Fig. 9 by a mechanism to be now described, and a like movement is imparted to-the link 94 througl1 the lever 98, link 99, and arms 97 and 90. A vertically movable rod 101 (Fig. 10) is guided in openings 102 and 103 in a shelf 104 above the cams and in a bracket 105 carried by the shelf. The rod is normally retained at the upper limit of its travel by a detent 106, engaging a notch 107 in the side of the rod. The detent is secured to an end of a rod 109 which is slidably mounted in a vertically disposed bearing plate 111 carried by the shelf. The

other end of this rod carries an armature 112 for a magnet 113 andv the detent 106 is normally pushed toward the rod 101 by a spring 114 coiled about the rod 109 and acting against the detent 106 and the adjacent face of the bearing plate 111.- A coiled spring 116, which constantly pushes the rod 101 downwardly, encircles the rod 101 and engages the lower horizontal face of the bracket 105 and a collar 115 mounted on the rod. A rod 110 is connected to the rod 101'by abar 110, which, as will be described in connection with the electrical wiring of the pin setting machine, controls in part the movements of a switch in the circuit supplying current to the magnets 71 whichlift the pins.

The lower end of the rod 101 is flattened to provide a leaf 118, adapted to engage and move a finger 119, provided upon the stub shaft 93, causing a movement of the mechanism controlling the position of the various fingers, (Fig.9). The finger 119 is bent over a notched plate 120, pivoted at- 121 on the inner face of the disk 53. Rearwardly of the pivotal connection between the plate 120 and disk 53, extends an 'arm 122, to

which an end of a spring 123 is fastened. The spring is fastened at its other end to a post 124 and serves to lift the notched end of'the plate 120 outwardly from the center of the'disk into engagement with the bent over end'of the finger 119. Two notches 125and 126 of appropriate form to be engaged by the finger' 119 are. provided in the outer edge of the plate 120. The finger nor- 'mally engages the notch 125 maintaining notch 107 in. the rod, permitting the spring 116 to pull the rod downwardly into position to interpose the leaf at the lower end of the rod in the ath of thefinger 119 as the disk rotates. his finger is thus moved *the balls and pins fallin carrier deliversthe pins and balls.

from the notch 125 into the notch 126, moving the links 96 and 94 from the position shown in Fig. 9, opening the finger 85 of the disk 53 and both fingers 67, 67 "of the disk 54. As the disks rotate the fingers 67, 85 and 67 are opened and the roller 64 is guided into groove 66 and finally engages and opens yielding finger 68 and passes into groove 65. During this portion of the revolution of the disks the pin setter frame is lowered until the magnets 71 contact or approximately contact with the tops of the standing pins and is raised carrying the pins, which have been attracted by the magnets, to elevated position. The pins are held in this elevated position throughout that portion of the revolution of the disks while "the roller 82 is passing through the groove 84 of the disk 53, during which the sweeper sweeps the alley and returns to inoperative position. After the roller 82 leaves the groove 84, the roller 64 enters the groove 66, lowers the frame to replace the pins in the exact position they occupied before the 'deadwood was removed. The denergizing .rent and the finger 119 is moved from the notch 126 back into the notch 125 by an arm 140, mounted upon the platform 29 between the disks (Fig. 9). When the fingers are operated for the removal of deadwood, a

finger 140' rigidly mounted upon the stub shaft 93 is moved into position to be struck by the arm 140. The engagement of this finger with the arm 140 causes the finger 119 to be reset in the notch 125 by the movement of the arms 95, 95' and connecting link 96 thereby returning the fingers 67 67 and 85 to normal position as shown in Figs.

8 and 9.

When the pins and balls. fall into the alley pit (Fig. 3), they drop either upon a continuously ,moving centrally disposed car-.

rier 127 or upon either of a pair of inclined walls 127, one of which is located upon each side of the carrier 127 in position to cause thereon to roll down mpon the carrier. he carrier moves always-toward the rear wall 128 of the pit in which is an opening 128' beneath. the

swinging bumper 23 and through which the The carrier .127 travels over rollers 129 and 131, the rearmost of which, 129, is provided at an end with a bevel gear 132, meshing with a bevel gear 133, fixed upon the end of an inclined shaft '134, continuously rotated from a. shaft 135 through a universal joint 136, connecting it therewith. The shaft 135 is mountedin suitable bearings upon the platform 29 and is continuously rotated from the main power shaft by suitable gearing designated generally as 137. As the pins and balls are delivered by the carrier 127 through the opening 128 they are received by an elevating mechanism located at the rear of the machine which deposits the balls upon the return track and the pins on the assembly shelf. (Figs. 3, 4.).

The elevating mechanism comprises a carrier 142 which is continuously driven from the main'power shaft 147 by a pair of large sprocket wheels 148 rigidly mounted on the main power shaft. The power shaft receives its power from the motor 28v through the sprocket chain 145 meshing with the sprocket wheels 144 and 146 mounted respectively on The shafts 143 and 135 (Fig. 2). The elevating carrier 142 comprises a pair of chains, each of which is trained over a sprocket wheel 148 and is composed of side bars 149 arranged in pairs and the adjacent pairs are pivotallyconnected by means of pivot pins 151. Each of the pins 151 forms a shaft'for a roller 152, the said roller being formed to fit between the teeth of the sprocket wheels 148.

The carrier operates partly inna casing which comprises a curved wall 153, the rear wall of the pit and a backwall 153'. The carrier travels alongside the curved wall and is guided thereby and by a pair of tracks 154, (one for each chain) the rollers moving between the tracks and the inner surface of the wall 153, as is possibly best seen in the lower right hand corner of Fig. 3. Upon a plurality of the pivot pins 151 are mounted the lifting flights 155. Each 156'. .The upper face is inclined to the outer face 160 at an angle slightly greater than 90 degrees so that pins andlballs resting upon the upper face will roll outward toward the outer face 160 and bear gently against the inner surface of the curved wall 153. The lower-face 156' is inclined to the face 160 at an angle much greater than 90 degrees and the upper and lower faces 156 and 156. are connected by two inner 1nclined faces 157 and 158, intersecting above the transverse center of the flight so that the lower inner face 158 is much longer than Viewing Fig. 4, wherethe bases'of the re cesses are indicated by dotted lines, it will be noted that the upper recess 159 extends from substantially the intersection of the two inner faces 157 and 158 to the outer face 160 of the flight and that its base is. so

inclined to the outer face 160 at an angle equal approximately to the angle formed by the faces 160 and 156. The lower recess 159' extends substantially from the intersectionof the faces 157 and 158 to the outer face 160 beneath and at a substantial angle to a perpendicular to the outer face 160. The inclination given the upper face 156 of the flight and. the inclination given the bottom of the upper recess 159 causes the pins and balls carried by the'flights to roll against and be partiallysupported by the wall 153 of the casing. The amount of support offered by this wall of the casing is,

however, reduced to a minimum in order to provide as little friction as possible to the movement of the carrier, and to this end the sprocket wheels 148 are positioned inwardly of the sides iof the alley and thev Wall 153 of the casingris' inclined slightly from the vertical to the said sprocket wheels. As the pins and balls are delivered through the opening 128 in the rear wall of these flights is secured at each side to a (if the F Jr0 e Carriel t y t pair of pivot pins a d xtg dgi dly f bled and ostled by the carrier until, one

.by one, they become lodged upon the flights and are carried up to discharge position as -w'1 ll now be described. The recesses 15 9 form seats for the balls and retain them in place on the flights, preventing movementendwi'se of the flights and inwardly of the carrier. The pins may be carried up either end foremost on the flights and as it is necessary in this embodiment of my invention that the pins move onward butt end foremost after delivery from the carrier I provide means for reversing the position of the pin as it is delivered from the carrier if its head end shouldibe foremost.

The:- wall 153 (Fig. 4) of tends .a substantial distance above the opening 128' on the return side of the carrier and on the other side above a shelf upon which the pins are collected. In the latter side of the casing is provided an opening 161, of suflicient. size to permit the bowling balls to" pass out of the casing and onto an incline"-162, leading to the top of the return track 163. The opening 161 is provided with a door 164 normally retained in When the flights are located '70 the casing ex- 120 closed position by a spring hinge 165. The spring of this hinge is of suflicient strength to maintain the door in closed position when a flight -155 carries a pin past the same but is not strong enough to prevent a bowling ball from opening the door and rolling by gravity out and onto the track.

When the pins carried by the flights reach the top of the wall 153 they are deposited into a chute 166 (Figs. 1, 17). ThisIchute is provided at its outer and upper sides with an upwardly inclined curved wall-167.

The wall of the chute adjacent the carrier is composed in part of the upper end of the wall 153. and in part of the wall 168. The upper edge of the wall 153 over which the pins roll by gravity when the flights carrying them pass thereby is curved to provide upwardly extending ends 169, 169

Eachpin lies on the flight with its body and head in contact with the upper face 156, and rolls outward against the wall .153 of the casing in a slightly inclined position lengthwise. If the head end of the pin is foremost when carried up by aflight it will engage the forward projecting end' 1690f the upper edge of the wall 153 when the pin 1 rolls off the flight and be retarded while the chute. This movement of the the butt end rolls rapidly about in the chute until the butt end of the pin is foremost in in is largely dueto the shape of the pm, of standard form, which produces a rapid movement when the pin is being reversed in position as it is delivered from the carrier. If the pin is carried up butt end foremost its head end will be retarded but slightly by the: projecting end 169' because the body rolls off the flight rapidly and by the time the body is inqthe chute, butt end foremost, the head slides away from the projection. i

From the chute each pin passes to the assembly mechanism (Figs. 1, 3, and. 11) which will now be described. At the bottom of the chute each pin asses over a swinging leaf 171 onto a table 1%2 located in the present instance just beneath the bottom of the chute. The swinging leaf is hinged at 170 on the table across the chute and is provided with an arm 173, extending outwardly through the outer wall .167 of the chute which extends over the table. .To the free end of this arm is secured an upwardly extending bent arm 174 which actuates a pawl 175 pivotally mounted on" an arm 182 oose on'shaft 180 to actuate the mechanism controlling the movement of-the assembly conveyer 176. A spring177 fastened to the arm 173 and to the wall 167 normally mainvtalns the free end ofthe leaf1 71 elevated above the table-172. When however, a pin slides down the chuteand falls onto the swmgmgleaf 171, the leaf is depressed and the upper end of the .174 is moved upper to the lower notch.

chain upon which are disposed outwardly extending blades 179 at suitable intervals to accommodatea pin between each pair.

The chain is trained over a pair of sprocket wheels 181 with which it meshes. Fixed also to the arm 182 is an arm 184 upon the end of which is an upwardly extending post 185, provided with a pair of notches suitably arranged to be'engaged by the rear end of the pawl 175, the lower notch maintaining the pawl out of engagement with the ratchet wheel and the upper notch maintaining the pawl in engagement therewith. The arm 184 is flexible to permit the post to yield as the pawl is moved from .one notch to the other. When the pawl is actuated by the bent arm 174 its rear end is moved from the lower to the upper notch. The teeth upon the ratchet wheel lift the front .end of the pawl when the pawl is retracted and moves the rear end of the pawl from the The end of the arm 182 is connected to a crank disk 186 by means of a link 187. Rigid with the disk is mounted a pinion 188 in mesh with a con.- stantly rotating gear wheel 189 mounted upon the main power shaft 147. It is apparent, therefore, that the arm 182 is oscillated continuously by the crank disk so that the pawl moves back and forth through an arc of given travel either above the ratchet wheel or in engagement with one of 1ts teeth. The travel of the ratchet wheel, which is of course coincident with thetravel of the pawl vwhen engaged therewith, 1s such that the conveyer is advanced one step each time the arm 174 causes the pawl to actuate the ratchet wheel 178. The ratio of the number of teeth of the pinion 188 to the teeth upon the gear 189 must be appropriate to permit an actuation of the ratchet wheel every time a flight 155 passes the entrance to the chute 166 as each flight may carry a pin to be delivered to the assembling mechanism. It will thus be seen that the pin actuates the assembly conveyer and when so actuated a blade of the conveyer engages the pin and moves it forward one step from the table on to the assembly shelf 191. The pins are thus disposed between the blades at the lower travel of the conveyer which moves them alon the shelf as the conveyer is advanced. T e shelf is carried by suitable brackets 192 pivotally tilting of the-shelf until a full set of pins has been collectedthereon.

At the front edge of the shelf is a pin193 (Fig. 18) which is engaged by the notched end 194 of a lever 195-pi'vota1ly mounted in the main frame above the shelf. To the upper end of thislever is pivotally connected one end of a link 196, the other end of this link being pivotally connected to one end of a lever 197 mounted upon the main frame adjacent that end of the shelf 191 distant from the delivery chute and this lever is provided with an upturned lip 198 at its free end which is disposed over the shelf in the path of travel of the pins and in position to be engaged by the foremost pm of a set when the last pin completing the set is delivered upon the shelf 191. The engagement of this finger by the foremost pin causes the shelf to be tilt ed and the pins to be deposited into distributing chutes 202 which deliver them to a distributer mounted above the pin setter frame as will be later described. It is obvious that since the tilting of the shelf 191 can be accomplished only by the engagement of the foremost pin at the end of its movement upon the shelf, the full quota of ten pins must be present on the shelf before this tilting action can occur. After the shelf has been tilted and the pins deposited in the distributing chutes, the shelf is returned to its normal horizontal position bynieans of a counterweight 201 fastened to the shelf. The distributing chutes 202, (Fig. 3) into which the pins fall as they slide from the shelf, are ten in number (one for each pin of the set) and they arrange the pins in the distributer in substantially the relation they have each with the others when theyare set upon the spots on the alley bed.

The distributer (Fig. 5) comprises a frame 203 and various other parts to be now described. The frame is formed of a plurality of horizontal parallel'longitudinally e rtending bars 204 disposed between and rigidly connected at their ends to horizontal transverse bars 205, fastened at their ends on the main frame at 206. Preferably eight longitudinal bars are provided evenly spaced apart to form seven channels, each channel being adapted to receive one or two pinsv in position to be deposited in the pin setter frame. Adjacent each side of the d stributing frame and extending parallel with. the bars 204 is secured a bar 200 which support the lower end of the chute 166 and the assembly shelf 191. The guiding plates 39 for the rods 38 and the bearings for the pulleys 36 are mounted on the distributing frame. At the end of each distributing chute 202 and within the channels formed by the bars 204 are provided a pair of blocks 207, secured to the inner-adjacent faces of the bars and having their upper faces beveled or curved and downwardly inclined from the chutes as willbe seen by comparing Figs. 5 and 7. l The pins are delivered by the chutes upon these blocks in inclined position, and are prevented from sliding toofar port 209 slidably mounted beneath the frame 203 and composed of a plurality of metal strips. The longitudinal strips 210 are normally disposed'centrally between and parallel to the bars 204, the saidstrips extending from the rear of the frame to beyond the foremost stop blocks 208 of their respective channels. All of the strips 210 are connected 'at the rear of the frame to a transversely disposed strip 211 and are connected intermediate their ends with shorter parallel transverse strips 212 to form the lattice-like frame. The central longitudinally disposed strip is extended beyond the front bar 205 of the frame beneath a plate 213 under which is secured a supporting plate 214 suitably insulated from the plate A leaf spring 213 extending transversely of the frame is fastened to plate 213; and the end of the strip210 slides upon this spring, the force of the spring being sufficient to sustain the end of the lattice-like support 209 above the supporting plate 214: when no pins are in the frame but not sufficient to'sustain both the Weight of the support and a set of pins carried thereby.

Viewing Fig. 5, the lattice-like support 209 is adapted to be moved toward the left to permit the pins, after being delivered to the distributing frame, to be deposited simultaneously in the pin setter frame. The mechanism for moving the lattice-like support for thispurpose comprises a bell crank lever 219 (Figs. 121 1) which is fulcrumed in vertical position at 220 to the side of an upwardly extending flange 221 of an angle iron 222 secured to the distributing frame 203, one end of the said angle iron being fastened upon the bar 204C nearest the left side of the pin setter frame and the other end upon the left bar 200. Adjacent the angle iron 222 an upwardly extending bearing bracket 223 is fastened and supports a sprocket wheel 224, which is eccentrically connected to an arm 225 of the bell crank lever 219 by a link 226 so that the revolution of the sprocket wheel will cause the bell crank to oscillate upon itspiv'otal connection with the angle iron 222. The other arm of the bell crank lever is made in the form of a finger 227' which slides freely in a slot 228 in a plate 229. This plate is rigidly con: 2 5.

vice is limited by a pin 234 which is rigidly secured to the plate 229 and which extends through an arcuate groove 235,in the device. Adjacent the locking device is provided a stop.236, fastened upon the plate 229. The step 236 isgprovided with an in; clined face, 237 upon its side distant from the locking device and the outer end of the stop 236 is spaced inwardly of the outer' .end of the locking device 232 when the device isdisposed in the. path of the finger 222.

A finger 238 preferably having a rectangular end is slidably mounted in a yoke 240 (Fig. 1) fastened to the distributing frame and is normally interposed between the locking device and the stop 236 to maintain the device in inoperative position and there'- by permit the finger 227 to reciprocate freely in the slot 228. The finger 2 38 is pushed-toward the plate 229' by a spring 239 and is provided at its end distant from the plate with an armature for a magnet 241 which, when energized, momentarily pulls the armature toward itself and moves the finger 238 away from the plate 229 against the force of the spring 239. This movement of the finger 238 withdraws it "from between the locking device 232 and the stop 236 and permits the spring 233 to pull the locking device across the slot 228' into position to lock the finger 227 in the end of the slot adjacent the lattice-like support. If the finger is at this end of the slot when the magnet 241 is energized the locking device engages it and locks it to the plate 229. If, however, the finger is not in this end of the slot when the magnet is energized-it engages the inclined edge of the locking device and moves the device about its pivot to permit thefinger to pass, the locking device returning immediately to operative position and locking the finger 227 to the plate 229 as before. As the finger oscillates, after being engagedby the locking .device, it imparts a reciprocating movement to the lattice-like support, which carries the support first toward the left of the pin setting machine out of normal position leaving the pins in the distributing frame unsupported and'then back into normal position again, at which time the locking device is automatically disengaged from the finger 227 and this finger 227 is again permitted to oscillate freely in the slot 228. As the support nears the end of its return movement mto a pin setter comprising the pin setter frame 26, a plan view of which is shown in Fig. 6. The pin setter frame is composed of relatively heavy outside bars 243 and longitudinally extending bars 244, the latter bars being equal in number to the numberof longitudinal bars 204 of the distributing frame; The bars 244 are secured at their ends to the outside bars of the frame and are arranged to dispose them parallel to and directly beneath the bars 204 of the distributing frame, thus dividing the space within the outside bars into seven spaces beneath and corresponding to the seven channels provided in the distributing frame. As the pins leave the distributing frame they are delivered to the pin setter frame immediately above the spots on the alley bed upon which the pins are subsequently to be deposited. The pin setter frame is mounted slightly in advance of the distributing frame as shown in Fig. 3, so that the pins may slide easily from the one frame to the other; Tent upwardly extending transversely curved guides245 are provided on the top of the pairs of bars 244 in position to form a stop to limit the forward movement of the pins as they slide into the pin setter frame and to aid in guiding the" pins into position upon the alley bed, as will be later described. Rearward of each upwardly extending guide is provided a 'piv otally mounted curved guide 246 on which the pins fall. These guides 246 are fastened beneath the bars 244, upon cross pieces 247 by hinges 248. As the pins leave the blocks 207 of the distributing frame they strike with their butt ends against the guides 245 and .then fall upon the guides 246 which support them in the position shown in dotted lines in Fig. 7. The fixed upright guides 245 and the pivoted guides 246 are preferably shaped in a suitable manner so'that each pair will engage a pin sufliciently and above its lower portion to properly center andposition the pin upon its spot on the alley bed. To this end I prefer to curve the guides transversely and extend them lengthwise sufficiently to engage the pins 72 at the shoulder 7 2' and also at the sides-of the head 7 so that the pins will be centered for proper spotting by engagement of'the guides with the upper part of the pin, the lower part being entirely free. 1

In order that the pins may be delivered to the alley in upright position, the following mechanism is provided. A yoke 249 (Fig. 6) is fastened at its center to the under or rear side of each of the guides 246 which receive the pins to be set up in the three front rows, the arms 251 of. the'yoke extending toward .the front of the guide, and an angle iron 252 is secured to the under or rear sides of all four of the guides 246 which receive the pins to be set upin the fourth or real-most row. Three forwardly extending brackets 253 are fastened to this angle iron between the last mentioned guides. Each of these three brackets is connected by a suitable link 254 with one of the arms 251 of a yoke 249, secured to a guide which receives a pin to be set in the third row, the two outside brackets being preferably connected to the outside arms of the corresponding yokes. Links 255 are pivoted to the inner arms 251 of the yokes secured to the outermost guides of this row and to the outer arms of the yokes secured to the guides which receive the pins to be deposited in the'second row. The inner arms of these yokes are similarly connected by links 256 to the arms 251 of the yoke secured to the guide for the single front pin. It is apparent, therefore, that if the angle iron 252 is moved to raise the rearmost row of guides, the guides of the first three rows will be raised also through the ,links 254, 255 and 256. The pins are retained in reclining position shown in dotted lines in Fig. 7 until. gi th sweeper and the pin setter frame 100 the pin setter frame is moved downwardly to adjacent the alley when the guides 246 are automatically elevated. by movement imparted to the angle iron 252 as will be later described and the pins permitted to pass from between the guides 245 and 246 into set position on the spots on the alley bed.

' When it is desired to reset the pins, the frame is lowered in a manner similar to that described in connection with the removal of deadwood except that the frame is moved to the position shown in full lines in Fig. 7 which is closer to the alley than is permitted when the frame is lowered to pick up the standing pins preparatory to the action of the sweeper in removing deadwood. This movement of the frame 1s accomplished by the cam 54 (Fig. 8), the roller 64 being diverted into a groove 257 provided in the face of the cam for the purpose; At the ends of the groove 257 are located the fingers 258 and 259 similar in construction and'operation to the fingers 6'7, and 68 of the groove 66. The finger 258 is the finger which is positively opened and closed to divert the roller 64 into the groove'257 or to prevent its entrance therein, while the finger 259 is merely controlled by the spring 261 similar to the spring 69 and similarly connected to the finger. Finger 258 is mounted on the stub shaft 100 which forms the pivotal axis for and is rigidly connected to the lever 99 constituting an element in i the connection between the links 94 and 96 m as has been previously described.

' As a necessary preliminary step to resetting the pins, the .alley bed and gutters must be cleared of pins, and to I this end the sweeper is moved along the alley in the manwe ner already described before the roller 64 enters the groove 257 to operate the pin setting machine for setting the pins upon the alley. A groove 250 Fig. 9) is provided in the disk 53 to impart this movement to the sweeper and is similar in all respects to the groove 84 which actuates the sweeper during the removal of deadwood. It is,

however, so located that the sweeping operation is completed and the sweeper returned 85 to normal position before the cam disks rotate through a. sufficient angle to bring the roller 64 into the groove 257 of the pin. setter frame cam 54. A finger 260 is provided at the forward end of the groove 250 so adapted to close the groove during the removal of deadwood and to direct the roller 82 therein when the disks are revolved to re-set the pins. This finger is rigidly to re-set the pins are normally maintained to open position. When the magnet 59 which controls the clutch 55 is'thrown into operation, the cam disks will, as has been described, make a single revolution causing 106 the roller 82 to be directed into the cam groove 250 of the sweeper disk to actuate the sweeper, and subsequently cause the roller 64 to be directed into the groove 257 of the cam 54 to move the pin setter frame 110 from upper position to adjacent the alley bed and back to upper position again. At-

tention is called to the fact that in the present embodiment the two grooves 84 and 250 of the disk 53 are identical in form, causing 118 the action of the sweeper to be thesame' in .both operations of the machine, and it will be hotedthat the groove 257 approaches nearer the center ofthe cam 54 than do either of the grooves 66 or 66 imparting, 120

as a result thereof, the longer travel to the pin setter frame which is desired in setting the pins. As the pin setter frame nears the bottom of this travel, the guides 246 are swung on their pivots to deposit the pins on'the spots by the following mechanism (Fig. 7). A link 263 is bent toextend over the'angle iron 252 and is pivotally secured atone end to the central bracket 253 and at its other end to one arm 264 of a bell I .mounted upon the shaft 93' which is con- 96 cranklever 265 which is fulcrumed in a I bracket. 267 mounted upon the rear of the fastened to the rear of the distributing frame. Upon the rod 268 are two stops, one

271 \being located within the pipe and the other 271 without of the pipe. The movement of the pin setter frame from the position shown. in dotted lines to the position shown in full lines in Fig. 7 causes the stop I 271 inthe pipeto engage a suitable stop 272 at the' lower end of the pipe, oscillating the lever 265 about its fulcrum in the bracket 267. This oscillation of the lever 265 acting throughthe link 263 will move the axes into vertical position. It will be noted that when the sto 272 upon the rod 268 is properly locate this action will occur substantially at the lowermost point in the travel of the pin setter frame, causing the pnirilils to be gently deposited upon the alley.

en the frame is returned to up er position, the engagement of the stop 2 1 upon the rod 268 with the end of the pipe 269 will oscillate the lever 265 in the opposite direction, returningthereby the guides 246 into position toreceive a new set of pins.

the pins standing upon the alley during the 7 pin setter frame.

As the magnets 71 must be disposed above operation of, removing the deadwood, I find it convenient to retain them normallyin this position. They must be moved out of,

the ,way, therefore, when the pins are to be deposited u .on the alley as has just been described. 0 this end the magnets 71 are carried by. and depend from a. frame 273 (Figs. 6, 7) which is mounted beneath the This magnet frame is rigld and iscomposed of a plurality of longitudinal bars 274 and shorter transverse bars 274'. The frame 273"is-slidably supportedin suitable brackets 275 fastened to the pin setter frame 25 and is automatically moved rearwardly when it is desired to deposit a new'setof pins 11 on "the alley from the pin setter frame by a ent link 276 which ispivotally connected at one end to a bracket 27 fastened ri 'dly beneath and to the said magnet frame 2 2'andatthe other end to an arm 278 riveted orfastened in suitable manner to the am 266 of the lever 265. The

.inovement of the lever 265 from the posi: tion shown in dottedlines to the position shown in full lines in Fig. -7 will cause the frame 272 and the ma et's' carried thereby to move to the right, -v1ewing Fig. 7,. out oftheway of the p ns. When the lever is restandingp ins when it is desired to remove the deadwood. a

In Fig. 15 I have shown a. system of wiring for the various magnets heretofore described, it being understood, however, that this wiring may be varied in numerous ways without departing from the spirit or scope of the invention or sacrificing any of its advantages. In this diagram 281 and 282 indicate respectively positive and negative main line wires from which power is delivered to the various circuits from a suitable source 283. 1 The various magnets are given the numbers applied to them in the foregoing description of the pin setting machine. Two switch buttons 284 and. 285

form the controlv and are preferably located r at the playersend ofthe alley,the' operaguides 246 upwardly about their pivotal 295 carried by the pin setter frame are adapted to contact therewith upon movement of the pin setter frame, the fingers and posts contacting only when the frame is in upper or normal position. When the spring finger 288 and the metallic post 293 are in contact, connection is made with a wire .296 which is connected to a finger 297, carried beneath one of the movable guides 246. The finger 297 is mounted in a non-conducting block 298, fastened to the underside of the guide and in this block is also mounted a flexible leaf switch 299 adapted to contact either with the finger 297 or with a similar finger 301 carried by the block. The switch 299 is normallyti contact with the finger 3 01 and is ada ted to be bent to contact with the finger 29 when pins are resting in the pin setterj frame, by a'movable stud 302 which extends through the guide and which if is pressed by apinmesting. therein against the switch 299, causing it to move out of contact with the finger .301 into contact with finger, 297. When the leaf switch is in contactwith the finger 297, connection is established between the wire 296 and a wire 303 which .leads tothe post 295. From the spring pressed finger 291 which contacts with'the post 295 when the pin setter frame is in upper osition, the circuit is completed through a line 304 leading to the negative gmain line wire 282.. Therefore, when the re-set button is pressed the currentpassing from the main linewire 281 through the magnet 59 energizes this magnet and throws the disks to rotate through one revolution whereby the roller 82 is' guided through the groove 250, operating the sweeper to sweep the standing and dead; pins from the alley, and the roller 64 is then directed through the groove 267 to re-set the'pinsl When the frame returns to upper position and the rods 293, 294 and 295 contact with the fingers- 288, 289 and'291, a separate circuit is established which automatically delivers. the pins from the distributing frame into I the pin setter frame by energizing the magnet 24-1. This circuit comprises the wire 286-leading from the main line wire 281,

a wire 305 leading from the wire 286 to the magnet 214 which controls the shifting of the lattice-like support holding the pins in the distributing frame in readiness to be received by the pin setterrframe, the wire 306 leading from this magnet to the spring 213', upon which the forwardly extending end of the central bar. of the lattice-like support is slidably supported and which is adapted to be depressed by the weight of the pins carried in the distributing frame into contact with the metallic plate 214, a wire 309 leading from the metallic plate 214 to the spring finger 289, a wire 311 leading from the post 291 which contacts with the spring finger 289 to the finger 301, which when no pins are carried by the pin setter frame is in contact with the leaf 299, the wire 303 leading from the leaf switch 299 to the post 295 'contactingwith the spring finger291, and

the wire 304 connecting the spring finger 291 with the negative main line wire 28 2. Itwill be apparent, therefore, when the pin" setter frame is returned to upper position after depositing the pins upon the alley so that no pin is resting upon stud 302 to depress the leaf switch 299 to break its contact with the finger 301 that, if there are pins in the distributing frame,-thecircuit just described will be completed to deposit a new set of pins in the pin setter frame. It will be apparent also that the pin setter frame can not be lowered to -re-set the pins except when it contains a charge of pins and that the lattice-like support beneath the distributing frame can not be moved except when the distributing frame contains a charge of ms. p When it is desired to remove the deadwood, the deadwood button is pressed and 304 to the negative main line wire. In this circuit the two magnets 59 and 113 are con nected in series with the main line wires so that both magnets will be energized, the

magnet 59 to operate the clutch and the magnet 113 to shift the fingers 258 and 85 which control the movement of the sweeper and the pin setter frame for re-setting and which are normally retained in open position, to closed position, and to move to open position the fingers 67, 67 and 85 which control the parts during the deadwood operationfl The magnets 71 whichlift the. standing pins during the removal of deadwood are energized by a separate circuit. The wire 314 leads from the positive main line 'Wire 281 to one terminal 316 of the switch 315. From the other terminal" 317, a wire 318 leads through the magnets 71to the negative main line wire 282. A suitable blowout or fuse 319 maybe interposed in the circuitif desired; The terminal 317 is' formed upon one arm of a lever 321 which is mounted to move in a vertical plane and which is constantly pushed about its fulcrum 322 by a spring 323 to bring the terminal 317 into "contact with the terminal 316. The lever 321 is rigidly connected to a the rod 110 which has been mentioned in describing the mechanism provided for arranging the fingers upon the cams for the removal of deadwood. The rod 110 is nor mally and positively held in elevated osi- \tion'by the bar 110' upon the rod 101 [Fig 10) thus maintaining the switch in open position. The rod 110 passes through an aperture in the end of the bar 110 and is insulated from the said bar by a non-conducting vbushing 324. A collar 325 fastened upon the rod 110 engages the upper face of the bushing 324 and supports the rod in upper position so long as the detent 106 maintains the rod 101 in inoperativeposition. The lever 321 and the rod 110 are further revented from being moved to es- 'tablish contact v between the terminals 316 and 317 by an arm 326 rigidly fastened to the lever at one end and having its other I the current passes through the following, 328 of the groove moves under the end of circuit; up the line 286 to the magnet 59, *fronfthe magnet 59 through a wire 312 to the magnet 113 and from the magnet 113 through a wire 313 to bne terminal of the deadwood switch, from the other terminal down the wirg 287, through the finger 288, rod 293, wire 296,,fiy1ger 297, leaf switch 299, wire 303, rod 295, finger 291 and wire the arm. The 'rod 11 0 and its support prevent the closingpf the switch 315 at all 53 and 54 for the remove of deadwood,
